4 Claims. (Cl. 41-1) My invention relates broadly to an apparatus for treating the surface of poles and particularly fishing poles.

One of the objects of my invention is to provide an apparatus by which stripes may be produced on poles for providing surface treatment of the poles.

Another object of my invention is to provide an apparatus for applying stripes to poles in a uniform manner wherein the stripes are spiraled about the pole at substantially equal space intervals along the length of the pole. v

A still further object of my invention is to provide an apparatus by which a pole may be rotated and simultaneously advanced with respect to a burner flame for bathing the surface of the pole with the flame at uniformly spaced intervals and producing on the surface of the pole a stripe in a carbonized area.

Other and further objects of my invention reside in the construction of equipment by which a pole may be rotated and advanced with respect to a burner flame for producing stripes thereon as set forth more fully in the specification hereinafter following by reference to the accompanying drawings, in which:

My invention is directed to a machine for processnited States Patent 0 ing poles, particularly bamboo fishing poles for imparting thereto a plurality of spirally disposed uniformly spaced stripes. The method of my invention involves the surface treatment of bamboo poles by application of angularly disposed sheaths of flame through which the pole is rotated and simultaneously lineally advanced. The flame bath to which the pole is subjected carbonizes the surface of the pole in narrow stripes spaced uniformly from each other along the length of the pole. The heat treatment thus provided has many advantages, among which I may mention the fact that the heat destroys the possible existence of worms or borersor other insects which tend to bore from within the bamboo pole and weaken the pole; the carbonaceous treatment tends to strengthen the pole and eliminate cracks. I have observed that when poles stock treated in accordance with my invention remain in the warehouse for a substantial length of time that the stock is well preserved as distinguished from original bamboo poles when stored for the same length of time and which are often attacked by vermin apparently secreted in the pith of the pole. The heat treatment of my invention destroys such vermin and germs that tendto develop in the poles. Moreover, the uniformly spaced carbonaceous stripes on the surface of the bamboo pole impart an ornamental appearance to the pole which greatly increases the sales attraction for the pole.

Referring to the drawings in more detail, reference character 1 designates the longitudinally extending trackway along which the machine of my invention lineally moves. A pair of spaced guide rails 2 are maintained on the trackway 1 and serve as a guide for the rollers 4b and 5b carried on depending shafts 4a and 5a supported on axes normal to the axes of transversally extending axles 4 and 5. The axles 4 and 5 are maintained on the chassis 3 of the machine and carry wheels 6 on opposite ends thereof. The chassis 3 carries a motor 7 thereon adjustably maintained in a saddle support 8 having depending end portions 8a and 8b. The saddle support 8 is connected with chassis 3 by a vertically disposed adjustable member 9 having screw threads 9a thereon co-acting with securing nuts 9b which fasten the vertically adjustment member 9 in a longitudinally extending slot 3a in the chassis 3. The chassis 3 carries a horizontally disposed bar 10 thereon screw threaded at the end thereof as represented in 10a and engaged by nuts 10b. The horizontally disposed shank of the bar 10 extends through slots in the depending end portions 8a and 8b which co-act with the bar 10 and the vertical adjustment member 9 to enable the motor 7 to be raised, lowered, or longitudinally shifted with respect to chassis 3 in selecting the position of motor 7 which is suited for the proper tensioning of the driving belt system.

The driving system includes a pulley 12 carried by the shaft of driving motor 7 over which drive belt 14 is looped for engagement of pulley 15 carried by transverse shaft 16. The shaft 16 is transversally journaled with respect to the chassis 3 in the journal shown at 17. The journal 17 is carried by a sleeve-like member 18 mounted on vertically disposed support 19 which is fastened to chassis 3 by means of fastening bolts 20. The support 19 carries a vertically extending bolt 21 which passes through the sleeve-like member 18 and is secured by means of fastening nut 21a. The support 19 carries a transversal journal 22 at one side thereof through which transversally disposed shaft 23 is journaled. The shaft 23 carries pulley 24 on the end thereof aligned with the driving pulley 26 carried by shaft 16. Driving belt 25 extends from driving pulley 26 and engages the driven pulley 24.

The shaft 23 carries a driving gear 27 thereon which meshes with a gear 28 carried by shaft 29 which is transversally journaled in the ball races mounted in the housing 31. The housing 31 is divided into a lower and upper portion 31a and 31b, respectively. The lower portion 31a is secured by fastening bolts 32 to the chassis 3. The lower portion 31a forms a housing Within which beveled gear 33 carried by shaft 29 operates in mesh with beveled gear 34 carried on the end of shaft 35 which extends longitudinally of the chassis and is journaled in ball races 36. Shaft 35 rotatively drives the spindle 37 shown more particularly in Figs. 6 and 7. The end of spindle 37 is slotted as represented at 37a for receiving a transversally extended bolt 37b and securing the gripping yoke 39 in position on the end of the spindle 37. The gripping yoke 39 is formed by means of two resilient arms terminating in gripping teeth 39a which operate to grip the inside of the bamboo pole 40 which is to be surface treated as shown more particularly in Figs. 1 and 2. The parts 31a and 31b of the housing are secured together by means of bolts 31c, and the shaft 35 journaled in ball races 36 is further supported in the abutment plate 38 fastened to the end of parts 31d and 31b.

The trackway 1 also forms a mounting means for the roller support 41 aligned with the spindle 37 and located beyond the end of the furnace 42 as shown in Figs. 1 and 2 to serve as a support for the bamboo pole 40 in alignment with the spindle 37. The bamboo pole 40 is thus maintained in a horizontal plane along which the pole may be advanced and revolved.

The furnace 42 consists of the refractory housing in which a central burner 43 is located and connected with a gas supply through pipeline 44 which is connected to a cut-off valve 45 with a source of gas. The gas is supplied under pressure to the burner 43 immediately behind the plate 46 which is provided with angularly inclined slots spaced one from another as shown at 47, 48 and 49 in Figs. 8-14. Because of the angular inclination of the slots 47, 48 and 49, the gas flame which flows under pressure from the burner 43 is forced in thin sheaths of flame in spaced parallel planes which strike the surface of the bamboo pole 40 as it is revolved and advanced in front of the furnace chamber as shown particularly in Figs. 1, 2, 11 and 12 whereby carbonized stripes are formed on the surface of the bamboo pole as represented in Fig. 11 at 40a, 40b and 400. Three such stripes are applied simultaneously and the pole revolved synchronously with the linear movement thereof so that a uniform pattern is applied to the surface of the pole consisting of three convolute spirals. These spirals are regularly spaced along the surface of the pole and impart heat to the pole destroying worms, borers or vermin and at the same time U strengthening the pole for resisting tendency to crack. The pole is tempered by the treatment prescribed herein and the effective life thereof considerably enlarged. At the same time an ornamental appearance is applied to the surface of the pole.

The chassis 3 is guided in its linear movement with respect to furnace 42 by means of rollers 4b and 5b carried on the ends of the depending shafts 4a and 5a projecting downwardly from the ends of axles 4 and 5 as indicated more clearly in Figs. 1, 2, 3, 5 and 12. Rollers 4b and 5b engage between the lineally extending guide rails 2 and insure the advancing of the pole in a linear path in front of the plate 46 which extends across the furnace chamber 42 and through which the spaced sheaths of flame are force flowed. In order to insure the synchronous advancement of the pole 40 with the rotation thereof, I provide on the end of shaft 29 peripherally grooved pulley 50, around which a cable 51 is looped. Cable 51 is secured at opposite ends to stakes 52 and 53 disposed in alignment with each other in a longitudinal pattern substantially parallel with the axis by which pole 40 is revolved.

The pulley as it revolves tends to take up the cable 51 at one side thereof and to release the cable at the other side thereof as a result of which the pulley 50 progressively advances in the pattern defined by the cable 51 moving the chassis 3 lineally as confined by guide rails 2 and correspondingly lineally advancing bamboo pole 40 while rotating the pole 40 at such a speed that the spiral convolutions of carbonized stripes are uniformly applied to the surface of the pole at a rate which avoids ignition of the pole.

The speed of linear movement of the chassis is controlled by means of a rheostat 55 interposed between the power supply circuit 56 and the lead 57 to the motor 7. The operator by observing the position of the stripes being formed on the pole 40 may increase or decrease the speed to insure the uniform spacing of the stripes formed by the bath of flame to which the pole is subjected as it passes the furnace chamber.

I have found the machine of my invention highly practical and successful in its operation for the production of uniformly spaced spiral stripes on the surface of the pole, and while I have described my invention in one of its preferred embodiments, I realize that modifications may be made, and I desire that it be understood no limitations upon my invention are intendedother than may be imposed by the scope of the appended claims.
